Cutaneous metastasis of a hypopharyngeal squamous cell carcinoma-unusual presentation.

Cutaneous metastasis are uncommon and account for only 2% of all skin cancers, but are extremely rare in hypopharyngeal carcinomas.

Additionally, the clinical presentation is widely variable, which can make an early diagnosis difficult.

Case for diagnosis. Suppurative nodule or something deeper?

The authors report the case of a 62-year-old man with a history of total left hip arthroplasty nine years previously presenting with a large infiltrated plaque on the posterior area of the left thigh with three months of evolution without systemic symptoms or elevated inflammatory markers. Computed tomography of the left lower limb revealed a 12-centimeter linear extension of the lesion to the posterior part of the left proximal femur. Prosthesis joint infection, although rare, is a surgical complication to be taken into account, even if the surgery was performed many years before.
